A uniformly charged conducting sphere of radius one metre has a surface charge density `14 mu m^(-2)?`. Find the charge on the sphere and total electric flux leaving the spherical surface.

Explanation

`r=1m, sigma=14 xx 10^(-6) cm^(-2)`
charge `q=sigma xx" area "=sigma xx 4pir^(2) =14 xx 10^(-6) xx 4 xx (22)/7 xx 1^(2)=1.76 xx 10^(-4)C`
Flux `=phi =q/in_0 =(1.76 xx 10^(-4))/(8.854 xx 10^(-12)) =1.98 xx 10^(7) C^(-1)m^(2)`
